CAMERA CASE.

Application filed October 8, 1920. Serial No. 415,692.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L,1313.)

To all whom it may concern: I

Be it known that I, AUGUST NAGEL, a citizen of the German Empire,residingat Stuttgart, Germany, have invented certain new and usefulImprovements in Camera. Cases (for which I have filed an application inGermany March 25, 1919; in England October 1, 1920, Patent No. 173,322;and in France September 30, 1920, Patent No. 525,238), of which thefollowing is a specification.

My invention refers to photographic cameras, and more especially to thecases of roll film folding cameras. Its particular object is a casing ofthe kind aforesaid made all in one piece, with the only exception of theouter sidewalls, the inner casing for the folding mechanism as well asthe film cartridge chambers and the rear wall of the camera consistingof a single strip of material such as sheet metal drawn or stampedandbent into shape, the flat portion of the said strip forming acontinuation of one of the end walls of the inner casing, while its freeend is applied against the free edge or else against the inner surfaceof the opposite end wall,

In the drawings afiixed to this specification and forming part thereof,two modifications of a camera casing embodying my invention areillustrated by way of example. In the drawings- Fig. 1 is a perspectiveview of one form.

Fig. 2 is a like view of a modified form.

Fig. 3 a longitudinal cross section of the casing shown in Fig. 1.

Fig. 4 is a plan view of the strip of ma terial forming the casing shownin Fig. 1

the inner casing bein already drawn or stamped, while the strlp formingthe continuation of an end wall of said inner casing is shaped ready forbending it into shape.

Fig. 5 is a longitudinal cross section according to Fig. 4.

Referring to Fig. 1 of the drawings, a is the inner casing designed foraccommodating the folding parts such as the slide, the

standards, the shutter, the stays etc. This said inner casing is formedby drawing or pressing into shape one end of a strip of material (sheetaluminum or the like) the rear wall 0 of said inner casing which servesas the bellows frame, being stamped out simultaneously. The referenceletters a, a", designate the end walls and g, 9 denote the side walls ofthe inner casing. The fiat part of strip 0? is bent around the saidinner casing from the rear, care being taken to leave room, next to thenarrowend walls a, a, for the film cartridge chamber is and m,respectively, by bendingsaid strip twice substantially in semicircularshape, while the intermediate portion b, which forms the outer rearwall, is flat and extends in parallel with and at a slight distance fromthe rear wall 0 of said inner casing. The end wall a is cut out at itsfree edge to give room for the free end Z of strip (Z which is slightlynarrower than the rest and of a length about. equalling the height ofthe said end wall a" and which is bent at right angles so as to lie flatagainst the inside of the said end wall (Fig. 3).

"The outer casing, which thus surrounds the inner one from the rear, isthen closed at both sides by means of separate covers (not shown) withflanged rims which are re movably connected with the casing.

In the modification disclosed in Fig. 2 the strip cl is broader than theinner casing, a flange 7, being formed at each side of said casingwhereby narrow lateral chambers are formed for the accommodation of themechanism actuating the inner parts of the camera.

The space h intermediate the rear walls 0 and b, respectively, servesfor the passage of the fiat portion of the film.

I claim:

1. In a roll film folding camera in combination,-an inner casing and anouter casing, excepting the covers of said outer casing, made all in onepiece.

2. In a roll film folding camera in combination, an inner casing and anouter casing, excepting the covers of said outer casing, formed of asingle sheet metal strip.

3. In a roll film folding camera in combination, a substantiallyrectangular sheet metal casing and a sheet metal strip integral withanend wall of said casing, said strip surrounding said casing from therear and its free end being joined to the opposite end Wall of saidcasing.

4-. In a roll film folding camera in combi- 5 nation, a substantiallyrectangular sheet metal casing and a sheet metal strip integral with anend Wall of said casing, said strip surrounding said casing from therear and being twice bent into semicircular shape so as to form filmcartridge chambers and its 10 free end being joined to the opposite endWall of said casing.

In testimony whereof I afiix my signature.

AUGUST NAGEL.
